EV Charging

EV Charging Infrastructure Design

Electrical design support for AC and DC EV charging infrastructure, from early feasibility and site layouts through to construction ready tender information.

AC & DC car charging

The right charging technology, correctly designed

Selecting the right charging technology is fundamental to a successful EV charging project. The appropriate solution depends on vehicle dwell time, charging demand, available electrical capacity, operational requirements and future expansion plans.

AC charging is typically suited to locations where vehicles remain parked for longer periods, including workplaces, residential developments, retail destinations and overnight fleet depots. DC charging is suited to applications requiring faster energy transfer, from public and destination charging through to fleet operations, logistics facilities and high-power charging hubs.

EV Design provides specialist electrical design for AC and DC charging infrastructure, supporting projects from feasibility studies and site layouts through to load and capacity assessments, DNO and iDNO application support, protection studies, electrical tender information and construction stage technical support.

Design scope

AC charging design and DC rapid charging design

AC Charging

Typically 3.6 kW to 22 kW per charge point

AC charging design for workplace, residential, retail, destination, fleet and public sector developments. Covers single-phase and three-phase charging installations, including higher power AC systems where required, with load management strategies for multi-point charging infrastructure.

Feasibility studies and site assessments
EV charging site layout drawings
Charger technical reviews
Load and electrical capacity assessments
AC cable sizing and distribution design
RCD selection and DC blinding assessments
TT earthing system design, where required
DNO and iDNO application support
Electrical tender drawings and specifications
Construction stage technical support

DC Rapid & Ultra-Rapid Charging

Typically 50 kW and above

DC rapid and ultra-rapid charging design for public charging hubs, retail destinations, fleet depots, logistics facilities, forecourts and commercial developments. Higher power charging installations require greater consideration of electrical capacity, protection, cable thermal performance and utility connections.
